My husband has been waking regularly in the early mornings now for months. Sometimes he settles back down after a trip to the toilet and a drink of water, but sometimes he is caught up in a vivid dream and will not respond to me at all. He starts walking about, moving small items from the bedroom into another bedroom and talking about where he has to go and what he has to do. It is hard not to get irritable with him as he doesn't respond to me or my suggestions to get back into bed. Have others experienced such things and is there an end to this phase of dementia?
